Answer:
Since the 19th century, the normal body temperature meant 98.6 degrees Fahrenheit (37°C). This number was given by a German doctor Carl Reinhold August Wunderlich, after examining millions of reading taken from 25,000 German patients. Later the doctors of the U.S. and Europe repeated the same experiment and their results were similar. Following which, it was universally accepted as the normal human body temperature.
However, as per the new study carried out by the researchers at Stanford University, the normal body temperature of human being dropped by 0.03 degrees Celsius and 0.29 degrees Celsius per decade, for men and women respectively. This means the body temperature of men today is 0.59 degrees Celsius lower than that of men born in the early 19th century and for women, it has dropped by 0.32 degrees Celsius from the 1890s to today.
